Answer:
0.01 is alpha level
Step-by-step explanation:
Given that a survey of a magazine of 1500 adults revealed that 12% chose chocolate pie.
i.e. p = proportion of people who like chocolate pie = 0.12
Margin of error = ±0.03
The value of q =1-\hat p , =1-0.12 = 0.88
The sample size n is given as 1500. Therefore, n=1500
The confidence level is given as 99%
Hence alpha = 1- confidence level
=1-0.99=0.01
Hence answer is 0.01
(arrange the data set from least to greatest)
0, 0, 2, 2, 3, 4, 6, 8
(find the median: *the middle number*)
Median: 2.5
Lower quartile: 1
Upper quartile: 5
Interquartile range : upper quartile - lower quartile = answer
Interquartile range: 5 - 1 = 4
So the IQR or interquartile for the following data set is 4.

Answer:
The correct answer would be the last one; x < 3.
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
11x - 3 < 30
Step 2: Add 3 to both sides.
11x - 3 + 3 < 30 + 3
11x < 33
Step 3L Divide both sides by 11.
11x/11 < 33/11
Therefor, the correct answer would be the last one: x < 3
Hope this helps!
